How to Fill a PDF programmatically using IronPDF

In this tutorial, we explore how to fill out a PDF form programmatically using the IronPDF library in Visual Studio 2022. After creating a console project and installing IronPDF via the NuGet package manager, ensure you have the latest version for optimal performance. Begin by importing the IronPDF library in your code file to enable its functionalities. Create a PDF document variable and open the desired PDF using the 'from file' function, passing the file path as a parameter. Extract the form using the form property and access the fields using IronPDF’s convenient indexing method. Assign values to each field using their specific index and save the updated document with the save as function. Running the project should show the PDF filled accurately with text fields neatly populated. This tutorial demonstrates how IronPDF can simplify the process, and for any further assistance, their support team is readily available.

Notes:

• Replace C:\path\to\your\form.pdf and C:\path\to\your\filled_form.pdf with the actual paths to the input PDF form and the output file where you want to save the filled form.
• Replace FieldName1, FieldName2, etc., with the actual field names from your PDF form.
• Ensure that IronPDF is installed in your project via the NuGet Package Manager to make use of its classes and methods.
